PESSARY Filed April 24, 1931 Patented Feb. 7, 1933 UNITED STATES GEORGEA. CLARK, OF ELWOOD, NEBRASKA PESSARY Application filed April 24, 1931-Serial 0. 532,597.

along the dotted line 7-7 of Figure 6 and The present invention relatesto anatomical devices and more particularly to pessaries.

The primary objects of the invention are to provide a device that willnot cause pressure on the tisues when applied to the parts, that willallow the uterus to assume any and all of its anatomical positionswithout pressure irritation or strain; which is freely movable thereinand sanitary; which when applied will stimulate uterine contractions,causing the expulsion of stale venous blood from within the uterinewalls and permit fresh blood to take its place. WVill promote musculardevelopment of the organ and induce a healthy tone to its varioustissues. Will not obstruct normal or abnormal secretions and maintain anormal cervical opening.

When applied to pathological conditions as, metritis, amenorrhea,dismenorrhoea, venous congestion, cervical stenosis and malpositions ofthe uterus, tend to return it to its normal state of health. Alsopromoting conception in sterile females, at a later date.

It will act as a stimulating element to the muscles and nerves, and as amassage to the endometrium, and is safe from liability of pressure toany and all parts of the uterus,

under any and all conditions and positions.

Other and further objects and advantages of the invention will beunderstood from the following detailed description, references being hadto the accompanying drawing forming a part thereof and in which:

Figure 1 is a side view of the new device attached to an applicatortherefor.

Figure 2 is a side view of a tubular portion of the applicator, certainparts thereof being broken away. s

Figure 7 is an enlarged fragment of the device shown in Figure 6 andshowing the looped end thereof turned at right angles to the showing inFigure 6, the view being taken looking in the direction of the arrows.

Figure 8 illustrates the method of applying the new device within awomb.

Figure 9 illustrates the new device in an operative position. V

Figure 10 illustrates the new device par tially introduced, and

Figure 11 shows the new device applied within a womb, the view beingtaken at rightan lesto the showing in Figure 9. I

eferringnow to the drawing for a more particular description, thenumeral mindicates a coiled wire spring detent which, when released,will assume substantially the contour shown in Figure 6, which is itsnormal circular shape.

The end of the coil spring indicated at 11 is restricted in a mannerwhereby the end thereof will not protrude beyondthe larger smoothcircumference of the coil, said restricted end being adapted to engageagainst the end 17 of a shaft shown in Fi are 3 as later described. Theother end o (the coil indicated at 12 terminates in a looped eye, the 7.

end of the wire of which is similarly'enclosed inwardly within the loop,the latter being adapted to removably receive a chain 13,

thereby permitting the fitting of a longer or shorter chain, toadjustthelength. thereof to different individual cases in accordance withanatomical and other conditions. The: end of the chain 13 is attached toa hood ring 1 5, the latter having an eye l i'central ly thereof forreceiving the chain 13, said hood ringis best shown inv Figures 4: and 5and it will be understood that by this means it is insured that the'hoodring will remain centrally with respect to the chain at all times-whenthe device is in an operative position. The hood ring15 is provided withan opening A therethrough which permits a natural flow of blood duringmenstruation periods.

The foregoing parts are plated with gold, or other like non-corrosivemetal, as is also the applicator now to be-described.

The applicator includes a shaftpshown in Fig. 3, and indicated at 16..Theshaftis provided with a round end 17 and. a handle 20 is cutaway asindicated at 21 thereby providing a slot 22 which is of substantially 10the same length as the shaft 16, the major portion thereof being brokenaway as illustrated in Figure 1.

In operation and use, the parts are assembled as shown in Figure 1, itbeing understood that at this time the coil spring detent 10 is inalinement with and carried upon the shaft 16. The looped end 12 of thedetent 10 at this time will lie in the recess 20 provided at the end ofthe tube 19, thus preventing the coil 10 from rotating upon the shaft 16while the latter is prevented from rotating with respect to the tube 19by means of the handle 18 of the shaft being engaged within the slot 22of the tube, as shown in Figure 1.

A swab of local anaesthetic is first applied to the mouth and within theneck of the uterus. The assembly shown in Figure 1 is then inserted, theoperator grasping the lever handle 18 in one hand and the tube member 19in the other. The tube 19 is advanced While the shaft 16 is heldstationary, thus causing the detent coil 10 to gradually free itselffrom the shaft 16 while assuming its natural circular contour, as shownin Figure 9.

After the tube'19 has been advanced and the detent coil entirely freedfrom shaft 16, the entire applicator is removed, the ring '15 at thistime being across the mouth of the womb while the detent 10 is in thecavity thereof, as shown in Figure 11.

To remove the device at any desired later date the same may be done byapplying traction on the chain with any conventional instrument.

The ring 15 may be in the form of a hollow ball, if desired.

.From the foregoing description it is thought to be obvious that apessary constructed in accordance with my invention is particularly welladapted for use by reason of the convenience and facility with which itmay be assembled and positioned, and it will also be obvious that myinvention is susceptible of some change and modification withoutdeparting from the principles and spirit thereof and for this reason Ido not wish it to be understood as limiting myself to the precisearrangement and formation of the several parts herein shown in carryingout my invention in practice, except as herein claimed.

What is claimed is:

p An intra uterine pessary, comprising a cireularly bent coil springclosed at one end,

2165 and a flexible element connected at one end In testimony whereof, Ihave afiixed my 7 signature.
